Overview
- A roof collapse at an under-construction Taratala warehouse left 16 people dead and triggered a Special Investigation Team probe that has identified poor-quality materials and a flawed casting pattern as likely technical causes.
- Investigators recovered the warehouse blueprint from a middleman and have begun forensic checks to confirm the document's authenticity and whether the built structure matched the approved plan.
- The SIT has formally sought records from the Kolkata Municipal Corporation and the Kolkata Port Trust, including plans submitted and whether soil testing was carried out, to trace how the project won permissions.
- Two key accused — owner Sambhunath Behra and former KMC OSD Kalicharan Banerjee — remain arrested while police have seized phones and documents and say Banerjee is not fully cooperating with questioning.
- Police are widening the inquiry into possible intermediaries and financial transactions used to secure approvals, and Jadavpur University structural experts have been assigned to identify specific design and construction flaws.
